NEW JERSEY, ASSIGNOR TO MARVEL SPECIALTIES NEWJERSEY, A C QRPORATION OF NEW JERSEY WINDOW onosnn Application filed April 21 1927, Serial No. 185,633. Renewed. September 4, 1929.

This invention relates to a window closer which is adapted to be operated by rain, the rain which runs down the'window pane being directed into a trip*device which, in turn,

(, releases a spring closing means which is put under increased tension when the window is opened. The device can be adapted'to various forms of sashes but I have illustrated it as applied to a sliding sash. The device has in addition to an automatic means amanually operated means for tripping the spring means for closing the sash.

The closure is adapted to collect water from the window in sufiicient quantity to operate the trip in short enough time to prevent any material damage by water entering an open window.

The device is illustrated in the accompanying drawings in which Figure 1 is a view of a window equipped with the closure. Figure 2 is an enlarged front view of the closure broken away to permit a contraction in the figure. Figure 3 is an end view of Figure 2 and Figures 4, 5 and 6 are sections taken on line 4 in Figure 2, showing various positions of parts in the setting and releasing of the device. Figure 7 is a top view, with the easing shown in section, of the parts illustrated in Figure 4. Figure 8 is a section on line 8-8 in Figure 7. Figure 9 is a perspective of a form of attaching means and Figure 10 is a perspective View of some parts of the tripping device to more clearly show their relative positions and their construction.

In the drawing the device is shown as adapted to close the sliding sashes of a window and I show the upper sash 10 and the lower sash 11. mounted under the lower rail of the upper one form being the pins 13 which are shown in Figure 2 which are fitted into plates 14 which are secured to the sash. The device 4 is spring operated and when the sash is open the device is put under increased tension and v for this purpose a flexible connection'is secured to a suitable anchor which may be the window frame or it may be the other sash. I

This connection is usually, in the case of two turn the shaft 17 is held bya ratchet'20 which, in turn, is held by a pawl in the form of a .water'in it descends and the pin 32 lifts up sashes, slid to the upper rail of the lower sash andis a flexible connection. In the drawing I show a steel tape-15 on each side fastened asat 16 to the lower sash.

This flexible connection is coiledaround the shaft 17 which passes through and is vrotatable in the body portion or case 12 of the closure and the spring 18 is put under greater tensionv when these connections 15. are pulled in the manner of a spring roller so that the spring 18 when released slowly coilsup and pulls, by means ofthe rod 17, on the connection 15 andcloses the sash or sashes, the spring. 18 being securedat one end rigidly to the casing and may be secured as shown in Figures" 2 and 3 by utilizing'the' inner ends of two of the pins 13'by passing the wire around them, the other end ofthe springboing secured. to the barrel 19'which'is secured to the rod or sl1aft 17 but hasa limited slid- .70

ing movement thereon to accommodate the elongation of the spring. One or both ends of the closure can beslid with a spring. 7

' To hold the parts against premature repin 21 on a plate22, pivoted at 23 and held in positionby spring 24 and this pawl 21 is released by a trip'e'ither manually operated or mechanically. operated by the weight of .7 water dripping fromthe sash.

To'provide for a quick accumulation of wayter I arrange av gutter25 extending for the-length of the closure and inclined toward the trip which is usually at the centre fin the housing 26. The gutter 25 projects so that it is directly under the outer edge of the The device is shown as upper sa'sh,the water runs down the gutter on 7, each side and is deposited in a small recepta- 7 sash and consists of a tube or barrel 12 which is held under the sash and against turning,

to position when it is released.

The receptacle 27, when weighted bythe the lever 33 pivoted on the rod-34-which spans the spacebetween thewalls 29 and 30 and thus swings back the hook 35. f i A The hook 35 normally holds a pin 36 of a pivoted cam 37.' The pin hasa "spring secured to it at one end, the other end of the spring being shown as secured to a cross bar 39. When the hook 35 is-swung back and releases the cam 37 the sam swings forward on its pivoted pin 38 and pushes the extension 40 of the pawl 22 so as to release the I pin 21 from the ratchet 2O andthe spring position against the influence of the weighted end or arm 33. This weight is sufficient to normally hold the hook against the influence of spring 38 as the said spring is arranged at .an angle thatznakes it easy for the hook 35 to retain the pin 36.

When the device is to be reset and the bucket 27 is in normal position, the. window is opened and when this takes place the ratchet moves around with the shaft .17. This ratchet carries a swinging plate 44. pivoted to the ratchetat 45 and thuscarried around with it. Theplatehas a pin'46 which extendsthroughia slot inthe ratchetand-has its end in the annularlrecess 47 in the ratchet.

(See Figure. 8.1) On the cam 37 is a pin 48 Which. extends through a slot 49in the wall 30 and is in the path of pin 46 as it also extends into' the recess 47.' When-the ratchet turns in a direction to wind up the spring the pin 46 pushes the pin 48 which swings the cam around untilthepin 46 clears pin 48.

By this time the .cam has been swung 3. A window closer comprising. a tube, a spring actuated rod in the tube, a flexible connection coiled on the rod, a pawl and ratchet for holding the rod when the rod is under spring tension, a trip for the pawl, said trip including a receptacle for Water,
